HOSE-NOZZLE FOR PNEUMATIC COTTON-PIGKING MACHINES.

Application filed March 19, 1918.

To all whom, it may concern:

Be it known that I, HARRY W. JORDAN, a citizen of the United States, residing at Syracuse, in the county of Onondaga and tltate of New York, have invented a new and Improved Hose-Nozzle for Pneumatic Cotton-Picking Machines, of which the following is a specification.

My invention relates to that class of cotton picking devices in which the cotton fiber is intended to be drawn from the boll into a tube or hose and thence to a receiving chamber by pneumatic suction. While such devices are. theoretically desirable for the purpose, they have never proved practically successful for the reason that the amount of suction that can be economically applied is insufficient, in many cases, to detach the cotton fiber from the boll in which it is held, and clean picking is, as a matter of course, essential to successful commercial op eration. I have found, however, that, even when the contents of the boll are not wholly detached therefrom the cotton fibers are more Or less straightened out by the suction so that some portion of them is drawn into the applied mouth of the hose nozzle and there held until it is taken away.

I take advantage of this fact to efiect the complete withdrawal from the bell of its contents by providing the collecting nozzle with means for grasping the fibers which have been drawn into it by suction so that upon withdrawing the nozzle from the boll in which the other ends of such fibers are held the entire contents of the boll are mechanically detached therefrom and may be then readily drawn into the nozzle and pass to the collecting chamber of the machine.

The invention will be best understood by reference to the accompanying drawings, Figure 1, orwhich shows alongitudinal elevation and Fig. 2, an end view of a hose nozzle with my invention applied thereto, Fig. 3 shows the same partly in section on the line 33, Fig. 2 and Fig. 4 is a diagrammatic illustration of a form of suction device which may be employed for drawing in the cotton.

Referring to the drawings, A indicates the collecting nozzle, which, as arranged for operating, is connected with a hose, B, leading to the collecting chamber F of the pneumatic device, which may be of any usual or suitable character, such as a rotating fan, G.

Specification of Letters Patent.

Serial No. 223,254.

Through an opening, a, in the wall oi the nozzle, A, adjacent to the mouth of the nozzle, passes a vertically movable member, C, which when in its depressed position is adapted to make contact, or nearly make contact, with the inner surface oi the nozzle. The end of the member, C, may be provided with teeth, 0, or otherwise so shaped or constructed that when the member is in its depressed position, any cotton fibers which have been drawn into the nozzle will be grasped and held between the end of the member, C, and the wall oi the nozzle. It will be understood that the member C is arranged to contact with the wall of the nozzle, A, just within, or substantially at, the open mouth of the nozzle, that is only so far removed therefrom that the relatively short cotton fibers can be grasped and held when their ends are drawn into the nozzle.

The grasping member, C, is connected with a spring, I), whereby it is lifted. "When the member, C, is in its fully elevated position its lower end is withdrawn into a boss, E, so as to be entirely outside the inner wall of the nozzle, A.

In using the device the open mouth of the nozzle, A, is presented to the cotton boll and at least some portion of the cotton fibers is drawn, by the action of the pneumatic de vice, into the nozzle. The spring, I), is then pressed down so that the member, C, is depressed and the cotton fibers are grasped and held between the end of the member, C, and the inner wall of the nozzle, A. The nozzle is then somewhat withdrawn from. the boll and the entire contents of the boll are mechanically drawn out by means of the fibers grasped by the member, G. The spring, l), is then released and the member C, is thereby retracted, its lower end being drawn up into the boss, B, so that the passage through the nozzle, A, is left entirely unobstructed. The cotton is then drawn by the action of the pneumatic device through the nozzle and hose into a receiving chamber, and the operation is re peated.

In this manner the cotton can be readily withdrawn even from those bolls in which it is so firmly held that it cannot be withdrawn by suction alone, and the operation of picking is rapidly and conveniently carried on.

It will be evident that the form or the member, C, may be widely varied without departing from the spirit of my invention Which, broadly stated, consists in the application to the collecting nozzle of means for positively grasping the partially withdrawn cotton fibers so as to enable the mechanical removal of the entire contents of the boll.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent is:

In a pneumatic cotton picking device the combination of a collecting nozzle, means. for drawing cotton fibers into said nozzle by suction, a movable member lying normally outside the inner wall of the nozzle adapted to make contact with the inner Wall of said nozzle and thereby seize and hold cotton fibers drawn into the mouth of the nozzle and a retracting spring for Withdrawing said member from said contact and to its normal position.

In testimony whereof I have afiixed my signature, this 16th day of March 1918.
